The "world" of a Bongard Problem is the type of thing the Bongard Problem sorts.
The OEBP has given names to some commonly occurring pools of objects. For example, we called the world of the top-left Problem on this page "shape_outline". (See that link if you aren't yet convinced there can be a pool of objects so commonly occurring in Bongard Problems that it is worth naming.)
A series of Bongard Problems may successively narrow a pool of examples further and further based on finer and finer rules.
In this picture, each Bongard Problem's world is the right hand side of the Bongard Problem to its left.
On the OEBP one can quickly create new names for pools of objects and assign them to any Bongard Problem's left hand side, right hand side, or whole. The OEBP also has a feature for keeping track of which worlds include one another as subsets. In this way, it is possible to indicate (for example) when the right-hand side of one Bongard Problem includes the world of another Bongard Problem, and it is possible to navigate the website by successively zooming in on finer and finer rules (as above).
NOTICE: Currently only administrators are able to add worlds to Bongard Problems or indicate which worlds are subsets of which others. This should change in the future.
What is the "world" of this Bongard Problem?
There is ambiguity in declaring the "world" of a Bongard Problem, just as there is ambiguity in determining the solution to a Bongard Problem. For example, is the world above "black polygons" or it it "black triangles and quadrilaterals"? Someone seeing all the images together might notice all the shapes are specifically triangles and quadrilaterals, or that specificity might not leap out as important.
We generally prefer to label Bongard Problems with whatever world is the most specific reasonable one, but it is okay to specify more than one world in particularly ambiguous cases. (However, do not arbitrarily label pages with worlds that are intuitively way too big; the world of the above Bongard Problem is not just "pictures".)
Worlds are narrow rules.
NOTICE: It would be helpful if someone could add .svg vector-graphics versions of images, in addition to the traditional hand-drawn bitmap files, to Problems with worlds relating to shapes and geometry. (But some visual Bongard Problems may be inherently about bitmap images.) See BP913 for related discussion.
